Conservatories
We design and install custom conservatories that seamlessly integrate with existing architecture while maximising natural light. Our structures utilise thermally efficient aluminium systems with U-values as low as 1.4, featuring slim sightlines and marine-grade options for coastal properties. Each project includes full planning assistance, building regulation compliance, and a 10-year insurance-backed guarantee.
Entrance Doors
Our premium composite doors combine security and aesthetics through advanced hardwood-core construction and multi-point locking systems. Available in 20 standard colours with custom RAL options, these PAS 24 and Secured by Design accredited doors feature adjustable hinges and dual-lock mechanisms for enhanced durability and energy efficiency across various property types.
Bespoke Windows
We supply and install made-to-measure windows in aluminium, uPVC, and timber formats, including heritage-style sliding sash and modern flush designs. Our systems achieve U-values down to 1.1 while maintaining period-appropriate aesthetics through authentic detailing and 30+ foil colour options that complement both listed buildings and contemporary properties.
Bi-fold Doors
Our Smarts Visofold 1000 bi-fold systems offer 133mm sightlines with Secured by Design certification when specified with laminated glass. These thermally broken aluminium doors provide seamless indoor-outdoor transitions, featuring flat-pack options for restricted access locations and marine-grade upgrades for enhanced environmental resilience.
Structural Openings
We create structural openings for kitchen-diners, extension connections, and doorway installations using cost-effective, minimally invasive methods. Our approach includes load-bearing calculations, temporary support systems, and coordinated integration with new windows or doors to ensure structural integrity and aesthetic continuity throughout the property.

Report
Hired John after getting quotes from larger companies who disappointed in their approach and customer service. In contrast John provided a competitive price, quality materials and great customer service. We agreed a design, timescale and payment plan upfront and all conditions were meet. Design changes did occur during the build but these were fitted in in without delay or undue strain on the budget. If I were in the need of more work then this company is one I would 100% use again

John installed some nice tilt and turn windows for me at a very reasonable price. I was quite particular in what I wanted and John was happy to accommodate. Highly recommended.
